Have you ever seen the sight of Jiangxi dragon sucking water into the sky?

Dragon suction, also known as waterspout, is a tornado formed above the water surface. Because of the high air pressure around and the low air pressure in the middle, the tornado will suck water into the hole in the center of the storm and then form a vortex around the axis. At this time, the tornado is like a cylindrical column of air, with the upper end connected to the thunderstorm cloud and the lower part connected to the water surface. It looks like a long dragon rising into the sky and touching the ground to absorb water comfortably.

Tornado is a vertical hollow rotating airflow between the bottom of the vertical cloud system and the underlying surface, and it is a disastrous weather phenomenon at local scale. Tornadoes can be found in tropical and temperate regions, including the interior of the United States, western Australia and northeastern India. Tornadoes are seasonally weak, and can occur in spring, summer and autumn.

Tornadoes can be divided into three types according to the different formation areas. One is produced on land and is called a tornado; One occurred during volcanic eruptions and major earthquakes and was called a fire tornado; The third is our protagonist today, a water-absorbing dragon, a waterspout produced on rivers and oceans.

A waterspout or waterspout can be simply defined as a water tornado, which usually refers to a non-supercell tornado on the water. Waterspouts may appear in oceans and lakes all over the world. Although waterspout is a kind of tornado by definition, it has less destructive power, but it is quite dangerous. Hoses can capsize and destroy ships, and they are more destructive when they touch land.

When the dragon absorbs water, the wind speed inside the vortex can exceed 200 km/h, and the instantaneous wind speed can sometimes reach more than 12. The water absorption duration of dragons is usually only a few minutes, but the longest is only a few minutes, accompanied by a huge roar, which is deafening. Therefore, although the diameter of the waterspout is small, it is also very destructive. It can cause the capsizing of sailing ships and has a great influence on maritime navigation. It can even take fish, frogs and insects in the water into the air and take them far away, and it will also drop strange rain such as Yu Yu and frog rain.

Usually, the period when dragon absorbs water intensively and frequently is summer, which can be extended to late spring and early autumn, usually from May to September. During this period, the weather is hot, and thunderstorms and strong convective weather occur frequently, which is very rare if it appears in winter.
